Windows 2000 provides support for the ISO 9660–compliant compact disc file system (CDFS), which supports LFNs as listed in the ISO 9660 Level 2 standards.
When creating a CD-ROM to be used on Windows 2000, you must adhere to the following standards:
All folder and file names must have fewer than 32 characters.
All folder and file names must be in capital letters.
The folder tree cannot exceed eight levels from the root.
File name extensions are not mandatory.
